This invention relates to improvement in spools or reels particularlyadapted for adheslve tape. kStrips of' adhesive tape are Wound upon aplurality of tubular cores mounted upon a suitable mandrel, then thecores, with the coils of tape, are separated and ends are applied to thecore, andthe object of this invention is a simple construction whichprovides a core of suflicient rigidity and toA Fig. 4 is a sectionalview on the line 4-4 of Fig. 1;

Fig. 5 is a side view of the core detached; Fig. 6 is an end Viewthereof;

Fig. 7 is a side view of an eyeletdetached;

Fig. 8 is an inside view of the same; Fig. 9 is va sectional viewillustrating a modiiied form of myinvention;

Fig. 10 is a sectional view showing another modified form of myinvention; Fig. 11 is an edge view of the same; and Fig. 12 is an insideview of the same. In carrying out my invention, I employ a core 15formed from a strip of sheet-metal and rolled to form a tube, the ends16 being turned in to form shoulders 17 To connect the edges of thecore, I form one-end of the strip with parallel slots 18 and raise themetal between the slots to form bridges 19. lThe other end of the stripis formed with tongues 20 which pass through the slots 18, below thebridges 19, and pressure is then applied to clamp the tongues by thebridges. In this way the tongues are bent transversely so as to be yfirmly interlocked. With the cores thus formed, I employ end-plates 21perforated for the reception of eyelets 22, the necks 23 of which arestruck outward to form fingers 24 arranged to engage with the shoulders17, so as to be rmly interlocked with the core.

It is obvious that instead of forming the Fig. 1 is a front view of areel or spool conl tending through said plates and formedwith eyeletsindependently of the end-plates 21, they may be Vformed integraltherewith, as shown in Fig. 9 of the drawings, in which the plate 21 isformed with a centrally-arranged inwardly-extending neck 28 provided 55with fingers 29 to engage with the shoulders 17, or, instead of forminga neck, the plate 27 may be formed with a series of inwardly-projectingfingers 30 provided with projections 31 to engage with the shoulders 17.With this'construction I provide a tube or core sufficiently rigid forthe purpose and provided with shoulders with which thelend-pieccs areirrnly interlocked.

I claim: 1. A spool, comprising a core formed from astrip of metalrolled to form a tube, the abutting edges interlocked and its endsturnedinward forming annular shoulders and endpieces provided with fingersengaging with the said shoulders, whereby the end-pieces are interlockedwith the core.

2. A spool, comprising a core formed from a strip of metal rolled toforma tube, one edge of the strip formed withl parallel slots form-l ingbridges and the other edge formed with tongues extending beneath saidbridges, the ends of the core turned inward, whereby annular shouldersare formed and end-plates provided with fingers engaging with said 3. Aspool, comprising a core formed from a strip of metal rolled to form atube, one edge of the strip formed with parallel slots forming bridgesand the other edge formed'with tongues extending beneath said bridges,the ends of the core turned inward, whereby annular shoulders areformed, end-plates applied to the ends of the core and eyelets ex- 9o'ingrs engaging with said shoulders.

In testimony whereof, I have signed this specification. f
